FREDRIOH BIOKLEIN, OF VALMEYER, ILLINOIS.

SCRUBBIN G-MA CHINE Specification of Letters Patent.

Patented March 31, 1908.

Application filed March 25, 1907. Serial No. 364,376.

To all whom it may concern:

Be it known that I, FREDRICH BIOKLEIN, a citizen of the United. States, residing at Valmeyer, in the county of Monroe, State of Illinois, have invented certain new and useful Improvements in Scrubbing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in scrubbing machines, and it has particular reference to a machine embodying a rotary brush and its driving means, a water tank, and a removable pan.

In connection with an apparatus of the above type, the invention aims as a primary object to provide a pan of novel construction for catching the dirt and water taken up by the brush.

The invention aims as a further object to provide a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description, in which reference is had to the accompanying drawings forming a part of this specification, like characters of reference designating similar parts throughout the several views, wherein,

Figure 1 is a side elevation of a scrubbing machine constructed in accordance with the present invention. Fig. 2 is a top plan view thereof. Fig. 3 is a central longitudinal sec tion thereof, and Fig. 4 is a detail perspective view of the removable pan above referred to.

The invention, in its practical embodiment, comprises a rectangular frame 1, upon the rear portion of which a water tank 2 is supported. Depending from the frame 1 are bracket bearings 3, arranged in corresponding pairs, said pairs conjointly supporting a transverse front shaft 5 carrying the loose wheels 6 and a transverse rear shaft 7 carrying the fast wheels 8. The frame 1 and its suspended parts are moved upon the wheels 6 and 8 by a handle 9 having its inclined sides pivoted, as at 10, to the rear portion of said frame. The shafts 5 and 7 are each projected beyond one of the respective wheels G and 8 on the same side of the frame 1, and the projecting portions of said shafts are fitted with respective sprockets 11 and 12, the rear sprocket 12 being of greater diameter than the sprocket 11 and serving to drive the latter by a chain 13.

The shaft 5 carries centrally thereof an elongated brush 14, the stock of which is fixed to said shaft whereby the brush is rotatable therein. A hanger 15 has its side arms journaled for rocking movement in the frame 1, said hanger comprising a U-shaped depending portion 16, having a horizontal lower bar 17 and being of slightly greater width than the brush 14, said hanger bein arranged directly in the rear of said brush at a slight distance away therefrom. A transverse bar 18 is mounted rearwardly of the hanger 15 in parallelism thereto and at a distance therefrom, the bar 18 also constituting a hanger. The hangers 15 and 18 conjointly support a removable pan 19, preferably constructed of sheet metal. The pan 19 is of novel construction and is best illustrated in Fig. 4, from which it will be seen that said pan comprises straight sides 20 and a bottom 21, curved to form both the rear and front end walls of the pan. Said pan at its rear end has a downwardly inclined extension 22 and at its front end is formed with a downwardly inclined scoop 28, the sides 20 being continued to form the sides of said scoop. The scoop 23 is disposed in closely associated relation to the brush l4 rearwardly thereof and conforms thereto in curvature, all the sides of said scoop partially overlying said brush and serving to initially receive the dirt and water collected thereby, and ,to prevent any of such dirt and water from remaining upon the floor after the passage of the brush thereover. The scoop 23 also partakes of the nature of a hook and in this function is engaged with the depending portion 16 of the hanger 15, the bar 17 entering the narrow recess 24 afforded between the bottom of the pan and the scoop and the sides of said depending portion overlying the sides 20. The extension 22 also serves as a hookv and is engaged in a similar manner with the bar 18. The pan 19 is provided with handles 25 upon the sides 21, by means of which said pan may be removed from the hangers 15 and 18 or replaced thereon when desired. In removing or replacing the pan 19, the front end of the machine is raised and the pan is moved on the bar 17 as a pivot until the extension 22 is disengaged from the bar 18 at which time, the bar 17 is swung slightly forwardly to allow of the pan eing swung downwardly, until the extension 22 is below the bar 18. The bar 17 is then swung rearwardly a sufficient distance to permit of the pan being raised so as-to allow of the disengagement of said bar from the recess 24 at which time, the pan is moved rearwardly over the bar 17, and thus en tirely removed from the machine.

A flexible pipe 26, controlled by a manually operated cock 26, is projected rear- Wardly from the tank 2 to the front part of the frame 1, said pipe being fixed to the handle. At its front end the pipe 26 communicates with a metallic pipe 27, which in turn is connected to the central portion of a horizontal tube 27 disposed at right angles there to. The tube 27 is arranged forwardly of the brush 14, Said tube is closed at its ends and along its body portion has closely associated apertures 28 for discharging the water in a fine spray in advance of the brush 14.

The manner of use will be readily apparent from the foregoing description. As the machine is pushed forwardly the brush 14 is rotated rapidly backward, by reason of the gear connections with the rear shaft 6. Said brush in its movement takes up the dirt and water and throws these products upon the scoop 23, from which, as the quantity increases, they are fed over the upper front edge of the pan 19 into the body thereof.

From the foregoing description, it will be seen that simple and efficient means are provided for accomplishing the objects of the invention, but while the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various minor changes may be made in the proportions, shape and arrangement of the several parts, without departing from the spirit and scope of the invention as defined in the appended claims What is claimed, is

A scrubbing machine comprising a wheeled frame, a horizontal shaft carried thereby forwardly thereof, a brush fixed on said shaft, driving means for said shaft, a transverse hanger rearwardly of said brush having a depending U-shaped portion, a transverse bar rearwardly of said hanger and a pan having a downwardly inclined rear extension engaging said bar, and a downwardly inclined forward scoop disposed beneath said brush and partially underlying the same, said scoop engaging said U-shaped portion as a hook.

In testimony whereof, I affix my signature, in presence of two witnesses.
